libarchive.public error even after installing libarchive in python

Question

I am getting an error when I am trying to do import libarchive.public. The below is the log text. I have installed libarchive using pip install libarchive. The help command shows the presence of public module in the library but while importing it still gives error. Can anyone help me on this what is the error about. I think I have done everything correctly.

I had to do it on Linux Mint as I could not find a solution for windows. The modified answer is below.

# Install compiler and tools
$ sudo apt-get install build-essential libtool python-dev

# Install cmake
$ sudo apt-get install cmake

$ wget https://github.com/libarchive/libarchive/releases/download/v3.4.1/libarchive-3.4.1.tar.xz
$ tar -xJf libarchive-3.4.1.tar.xz

# Configure using cmake...
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local ../libarchive-3.4.1

# Now compile and install...
$ make
$ sudo make install

$ sudo sh -c 'echo /usr/local/lib > /etc/ld.so.conf.d/libarchive3.conf'
$ sudo ldconfig

$pip install python-libarchive

Latest libarchive download link can be found at this URL: http://www.linuxfromscratch.org/blfs/view/svn/general/libarchive.html
